Glue frame injection mold and side face glue feeding structure thereof
Technical Field
The utility model relates to a glue frame injection mold and side advances glued structure thereof.
Background
The display generally includes a back plate, a light source, an optical module, a plastic frame, and a liquid crystal panel, wherein the plastic frame is formed by injection molding. The existing glue frame injection mold adopts a front glue inlet mode, so that the structure of a glue product can be arranged on the front surface of a glue frame, the front surface of the glue frame is uneven, the problem that the liquid crystal panel is assembled on the front surface of the glue frame in an uneven mode is caused, and the overall assembly quality of a product is affected.
SUMMERY OF THE UTILITY MODEL
In view of the deficiencies of the prior art, an object of the utility model is to provide a guarantee to glue positive smooth frame injection mold of gluing and side and advance gluey structure thereof.
In order to achieve the above object, the utility model discloses a technical scheme is one: the side face glue inlet structure of the rubber frame injection mold comprises a male mold plate, a mold core and four sliding blocks, wherein the mold core is fixedly installed in the center of the male mold plate, the four sliding blocks are slidably installed on the male mold plate and are respectively located on the periphery of the mold core, the four sliding blocks and the mold core are combined to form a cavity, and a main branch flow passage, a plurality of secondary branch flow passages communicated with the main branch flow passage and a plurality of submarine gates correspondingly communicated with the secondary branch flow passages are arranged on the sliding blocks.
Preferably, the glue inlet of the submarine gate is circular or rectangular in shape.
Preferably, the four sliders comprise two short sliders and two long sliders.
Preferably, the short slide block is provided with three secondary runners distributed at intervals and three corresponding submarine gates.
Preferably, five secondary runners distributed at intervals and five corresponding submarine gates are arranged on the long slide block.
In order to realize the above purpose, the utility model discloses a technical scheme secondly: a rubber frame injection mold comprises the side surface rubber inlet structure.
Compared with the prior art, the utility model discloses following beneficial effect has: the glue inlet of the glue frame is designed on the side face, so that the front face of the glue frame is free of protruding residual materials and smooth, the problem that liquid crystal glass assembled on the front face of the glue frame is not smooth is solved, and the requirement for the flatness of a display product is met.

Detailed Description
In order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The first embodiment is as follows: as shown in fig. 1 to 6, a side glue feeding structure of a plastic frame injection mold comprises a core plate 10, a mold core 20 and four sliding blocks 30, wherein the mold core 20 is fixedly installed at the center of the core plate 10 through bolts, the four sliding blocks 30 are slidably installed on the core plate 10 and are respectively located around the mold core 20, the four sliding blocks 30 and the mold core 20 are combined to form a cavity 40, and the sliding blocks 30 are provided with a main branch runner 301, a plurality of secondary branch runners 302 communicated with the main branch runner 301, and a plurality of submarine gates 303 correspondingly communicated with the secondary branch runners 302.
In the first embodiment, for convenience of manufacturing, the glue inlet of the submarine gate 303 is circular or rectangular, please refer to the end shape of the submarine gate material 503 in fig. 5 to 6.
In the first embodiment, the four sliders 30 include two short sliders 31 and two long sliders 32, three sub-runners 302 and three corresponding submarine gates 303 are disposed on the short sliders 31, and five sub-runners 302 and five corresponding submarine gates 303 are disposed on the long sliders 32.
The working principle of the first embodiment is as follows: during injection, the rubber firstly flows into the plurality of secondary runners 302 from the main runner 301, then flows into the submarine gate 303 from the secondary runners 302, and finally flows into the cavity from the submarine gate 303; during demolding, due to the included angle of the submarine gate 303, the rubber frame 50 and the submarine gate material 503 are automatically sheared and separated through the rubber ejection frame 50. As shown in fig. 7, since the glue inlet of the glue frame 50 is arranged on the side surface, the front surface of the glue frame has no glue inlet and is flat without protrusions; as shown in fig. 8, the liquid crystal panel 60 is also flat when attached to the front surface of the bezel 50 by double-sided adhesive.
Example two: referring to fig. 1 to 6, a plastic frame injection mold includes the above side glue feeding structure.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any person skilled in the art should not depart from the technical scope of the present invention, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention should fall within the scope of the present invention.
